This invention relates to a new and useful improvement in adding-machines, being designed particularly as an improvement upon the machine shown and described in United.

States Letters Patent granted to IV. WV.

Hopkins, No. 683,939, dated October 8, 1901. Our present invention consists in providing an error or correction key to the adding-machine of the said Hopkins patent, whereby when an example is set up on the keyboard 4 the same may be taken out of the machine by operating the said error or correction key. By pro iding the said machine with an error or correction key it is possible by the manipulation of said key to retain totals in the machine to be reprinted and carried forward. In the Hopkins patent aforesaid no means are provided whereby an example erroneously set up on the keyboard can be taken out of the machine, thus rendering it necessary to 5 print the error on the record-strip and make the correction in the total of said error by a pen or pencil after the strip is removed from Fig. 8 is a sectional view the machine. Furthermore, in said patent no means are provided for reprinting the total and carrying the total forward as the heading of another column; but, on the contrary, when a total is obtained the machine is automatically cleared, the adding mechanism being restored to Zero position.

We will describe briefly the operation of the said Hopkins patented machine as shown in the accompanying drawings for the purpose of afterward explaining the operation of our invention, which is intimately identified with certain of the moving parts of said patented machine.

In the drawings, 1 indicates the base, and 2 the side frames, in which latter are journaled the several shafts of the machine.

3 indicates what are known as the orderkeys, which keys, nine in number, are arranged to control the highest order of the example set up in the machine. Referring to Fig. 3,, it will be seen that the two order-keys at the right-hand side are white, indicating the cents and dimes, respectively. The next three keys are colored--say, for instance, reek-indicating units-dollars, tens-dollars, and hundreds-dollars. The next three keys are white, indicating thousands, tens of thousands, and hundreds of thousands, and the next key at the extreme left is colored, indicating the order million. In front of these order-keys are the number-keys 4, bearing numerals, starting from the left, from 1 to 9, inclusive, the key at the extreme right having the character 0. In setting up an example on the keyboard the order-key is first operated to set the control-carriage in the machine, as described in said patent aforesaid, aftcr which the number-key indicating the number of that order to be registered in the machine is operated, and the successive operation of the number-keys will register successively lower orders in the adding mechanism. For instance, if an item of live hundred and thirty dollars and forty-one cents was to be placed in the machine the hundreds-of-dollars order-key, which is the middle key of the row, would be pressed, after which the 5 key, the 3 key, the 0 key, the 4L key, and the 1 key would be successively operated. Then if five cents were to be added as an item the first key at the right of the line of order-keys would be operated and 5 in the row of number-keys would be operated. Whenever an example is set up on the keyboard by the successive manipulation of the order and number keys as above described, the handle 5 is pulled forward by the operator, which effects the printing of the items on a strip of paper, disengages the totalizer-trains from the item-trains, and restores the item-trains to Zero position, the final or return movement of the handle reengaging the totalizer and item trains for another operation. The handle also operates the carrying devices identified with the totaliZer-trains which are employed for transferring a number from a train identified with a column of lower order to the next adjacent train identified with a column of higher order.

Referring now to Fig. 1, 6 indicates a strip of paper which is fed from a roll by feed-rollers 7, said feed-rollers being operated at each operation of the operating-handle by a pawl 8.

wheel and provided with a pin 13. designed to cooperate with a restoring-arm 14:, extending from the shaft upon which the gears 12 are loosely mounted. WVhenever an item is set up in the machine, the gear 12 is rotated proportionately to the position of the operated number-key. the operated gear of course being identified with thecolumn resultingfrom the manipulation of one of the order-keys 3. The item-trains thus move a predetermined .distance upon the operation of a key identified therewith, and when the handle 5 is manipulated the item-trains are restored to Zero position by the arms 14: engaging the pins 13,.as is fully explained in said Hopkins patent referred to. 15 indicates a wheel in the totalizer-train normally in mesh with a gear 12 of its corresponding item-train, so that when the item-train is driven the totaliZer-train is correspondingly driven; but before the item-train is restored the totalizer-train is disengaged therefrom, so as to retain the total in the totaliZer-train. Otherwise the restoration of the item and totalizer trains would not only restore the itemtrains to zero position, but take the item out of the totalizer-train. The several gears 15 constitute the totalizer-trains identified with the orders comprehended within the capacity of the machine and are loosely mounted on a shaft 16, which carries Zero-arms 17, said zeroarms being used in taking a total by reversely rotating the totalizer-trains. To effect the printing upon the dual movement of the itemgears 12, which in placing an item in the totalizer-trains act as drivers for the type-wheels and for the totalizer-gears, but which in the taking of a total act as transmitting-gears whose movement is controlled by the extent of movement of the totalizer-gears connected therewith, and consequently the reverse rotation of the latter will reversely rotate the type-wheel, the type-wheel is provided with two sets of printing characters, as described in said patent. Both the item-gears 12 and the totalizer-gears 15 in the machine shown, which is designed for use in connection with the decimal system, have twenty teeth. The totaliZer-gears 15 are provided with trips 18, so that when a totaliZer-gear is moved a distance of ten teeth one of the trips 18 will actuate a pawl of lever 19, which cooperates and depresses a detaining-pawl 20, identified with a transferring slide-bar 21 of the next adjacent totalizer-train of higher order. This bar 21 (and there is a bar for each totalizer-gear) is provided with teeth in the path of movement of the totalizer-gcar, thus constituting said bar a rack, so that when a wheel of lower order trips the pawl 19 the detaining-pawl 20 will release the rack-bar 21 of the next adjacent train of higher order and when the totalizer-trains are disengaged from the itemtrains to enable the restoration of the itemtrains the rack-bars 21 will be restored, and such of the rack-bars as have been tripped, as before described, will move their engaged totalizer-trains a distance of one tooth, thus advancing the train of higher order. Of course such rack-bars 21 as have not been tripped will remain stationary and merely serve to lock their associate totalizcr-trains against displacement. The totalizentrains are carried in a rocking frame 22, pivoted at 23, and the means for rocking said frame, so as to elevate the totalizer-trains out of mesh with the item-trains, consists of a shaft 24, having a Hat face for supporting the frame 22. \Vhen this shaft is rocked, the frame is elevated, and as the shaft carries a plate said plate will engage projections 26, extending from the rack-bars 21, which have been actuated, and restore said rack-bars and actuate the totalizer-trains after the frame 22 is elevated. 27 indicates the total-key, which is prevented from being operated when the operating-handle 5 is in other than a home position by means of a link 28. connected to a rock-arm on the end of rock-shaft 24C, said link having a cam-face (see Fig. 3) which actuates a locking-pawl 29, having a shoulder designed to occupy a position under the total-key 27 whenever the operating-handle 5 is in other than a home position.

e have endeavored in the above to briefly describe the operation of the machine shown in the said Hopkins patent so far as the parts of said patented machine are related to or connected with our improvements. \Ne have not gone into a detailed description of the entire machine nor of the operation of the numerous parts thereof, some of which are not shown in the accompanying drawings, because the same do not relate to nor are they connected in any way with our improvements. We rely upon Patent No. 683,939 for a more complete explanation of the machine, as we do not herein claim any of the parts above referred to, except as such parts may affect and be combined withelements of our improved error-key construction, all as will hereinafter be more particularly pointed out and afterward specified in the claims.

From what has been said above it is evident that to correct an item erroneously introduced by operating the wrong keys parts must operate in a particular way or be prevented from operating, as the case may be. In the correction (taking out) of a wrong item certain parts must upon the next operation of the handle be operated to (a) perform their usual functions, (6) to perform different functions, or (c) not perform any function at all..

The following briefly describes the effects produced by operating the error-key; also, the actions of the machine consequent upon the manipulation of the handle:

First. The operation of the error-key causes the totalizer-trains to remain in mesh with the item-trains. The subsequent operation of the handle in restoring the item-trains also rotates the meshed totaliZer-trains and takes out the item last introduced therein.

Second. The operation of the error key trips all the transferring devices, which insures clearance upon the reverse rotation of the totaliZer-wheels when the handle is subsequently operated. The latter operation restores all the parts to normal position, or the position they occupied before the keys were operated to place a wrong item in the machine.

Third. hen the error-key is operated, the type-hammers are not permitted to make a record of the example erroneously set up in the keyboard. although the hammers make a printing stroke upon the subsequent operation of the handle.

Fourth. When the error-key is operated, the paper will not be fed. Thus no blank space occurs in the record indicating that an error had been made and corrected, although the feed-pawl is vibrated, as usual, upon the subsequent operation of the handle.

Fifth. When the error-key is operated, the total-key is locked against operation and is only released when the handle is operated and has completed its work in taking out the wrong item.

Sixth. WVhen the error-key is operated, the error-key is locked until the operating-handle completes its movement.

In the following description we will assume that an example has been set up on the keyboard and is in the item and totalizer trains. To take this item out of the machine and restore the machine to where it was before the item was set up in the keyboard, it is only necessary to depress the error-key 30 and operate the handle 5. 1n the following description we will describe the construction of our improven'icnts under ap 'n'opriate headings as outlined above.

ilM/ZIAZMI/MIg angrt m/mzt between totalz'e'cr and item trains.-.ll1e correction-key 30, which extends through the casing of the machine, is arranged upon the end of a lBVGl'3l, pivoted at 32. This lever has a lateral extension 33, which cooperates with a pin 34, mounted in a plate 35, upon a rock-shaft 36. The rear end of this plate 35 forms a finger which cooperates with a lever 37, suitably pivoted in a slotted post secured in the frame. Lever 37 has a cam-face 38 for cooperating with the finger 35, the lower end of said lever engaging a groove in a collar 39, feathered upon and slidable longitudinally on.the shaft 24, heretofore described. This collar'39, as shown in Fig. 8, has a flat face 40, and when the shaft 2% is rocked in the ordinary operation of the machine this flat face &0 elevates the totalizer-frame to effect the separation of the totalizer and item trains.

By the above construction when the errorkey is depressed the shaft 36 is rocked, causing the finger 35 to ride up the cam-face 38 and rock the lever 37, so as to slide the collar 39 on the shaft 2e and move the flat face 4C0 from under the frame 22, so that upon the next operation of the handle while the shaft 24 will be rocked the frame 22 will not be elevated, and in its lowered position the engagement between the totalizer and item trains is preserved. As the operating-handle will in the ordinary operation of the machine restore the item-trains to zero, it will be obvious that such restoration will actuate the meshed totalizer-trains and take out of said totalizer-trains the item erroneously set up on the keyboard. Thus so far as this fea ture of the invention is concerned the item and totalizer trains stand where they were before the example was erroneously set up on the keyboard, and the keyboard is cleared.

flipping t/w zf/"(rnsfrm-i'ng devicesn-The rock-shaft 36 is flattened on its under side and cooperates with projections &1 on the pawls 19, (see Fig. i,) so that whenever the error-key is depressed all of the pawls 19 are actuated and all of the rack-bars 21 are released. The release of the rack-bars is of no importance, being merely an incident to the raising of the pawls 19 out of the paths of movement of their cooperating trips 18 on the totalizer-gears, so that when the totalizergears are restored the pawls 19 will not interfere. 1f before the erroneous example was set up on the keyboard a totalizer-wheel stood at 9 and the erroneous example moved it a distance of one or moreteeth, so as to trip its cooperating pawl 19 in readiness to actuate the totalizer-train of higher order upon ITO the next operation of the operating-handle, it will be obvious that when the totalizer-train was restored to its former position it would bemoved back the same distance it had been moved forward to wit, to its 9 positionand so far as the actuated pawl and its cooperating rack-bar are concerned they stand tripped, and such position would mean nothing to the error-key and its connections except lessening the work of the error-key in operating the said parts.

Present my t/ze opmwt/rm of 2 /10 type-7mmmers.- We do not with our invention in correcting an example set up on the keyboard throw the type-hammers out of commission, because when the example is set up one of the first things to be done by the n'ianipulation of the operating-handle is to trip the type-hammers to effect a printing impression. Therefore with this condition to meet we prefer to let the machine operate as originally designed, and instead of throwing the type-hammers out of commission interrupt them and prevent them from making a printing impression at the commencement of the stroke of the operating-luindle. This we accomplish as follows: Referring to Fig. (3, it will be observed that the totalizer-shaft 16 at one end passes through the slotted end of a link 4.2, which link is connected to a lever L3, pivoted at 44k. Lover 43 engages a rock-arm as, mounted upon a rock-shaft 46, said rock-shaft carrying a bail or yoke 47, the cross-piece of which is normally in the path of shoulders 18 on the typehammers. Thus whenever the totalizer-trains are held in mesh with the itemtrains the link 42 is not actuated and the yoke L7 remains in the path of the shoulders on the type-hammers, and such type-hammers as may be actuated simply strike with their shoulders l8 against the yoke and do not make a printing impression. Thus the yoke provides a buffer or stop. An obvious equivalent would be a series of rock-arms with stop-pins, one for izer-trains out of mesh with the item-trains.

The next thing is to trip the type-hammers. XV hen the totalizer-frame is elevated through the link 42, lever 4E3, &c., the yoke 4;? is raised out of the path of the shoulders 4:8 on the typehammers and permits said type-ham mers to strike their blow and make a printing impression.

RwtcZw'Jm/ Z /w paper-feed in OZMICIZ'Zl L. As before described, the pawl 8 cooperates with and drives the ratchet-wheel of the paper feed rollers at every ordinary operation of the handle 5. Referring to Figs. 1 and 6, it will be seen that the spring-pressed level-e9 carries a stud 50 on its upper end, which stud cooperates with a cam-face in the lower edge of lever a pin 51 on the link 4:2. in the ordinary operation of the machine the totalizer-trains are lifted and link as elevated, which depresses the stud 50 out of engagement with the paperfeeding pawl 8 and permits said pawl to engage and actuateits cooperating ratchet-wh eel. When the totaliZer-trains are left in engagement with the item-trains upon the operation of the error-key it will be obvious that stud 50 will not be depressed out of engagement with the pawl 8, but will remain in position to render said pawl inoperative when the operating-handle 5 is manipulated. Thus while the operating-handle reciprocates the paperfeeding pawl S in the usual manner said pawl is not in operative relation to its co perating ratchet-wheel, and consequently the paper is not fed when an error is corrected on the keyboard. The record will not have a blankspace to indicate an error having been made on the keyboard, the paper remaining stationary, so that the next item printed thereon will strike in its proper position immediately under the preceding item.

Locl'zlny 257m tom/ivy.The lever 31 is provided with an extension 52, whose forward end is preferably bent at right angles and provided with a cam-face 53, (see Fig. 7,) which cooperates with a pin 5% on the locking-pawl 29, so that whenever the error-key is depressed the pawl 29 will be thrown inwardly to place its shoulder under the total-key 27 and prevent said total-key from being operated. This result is the same as that produced by the cam-link .28, only that the camlink 28 depends for its operation upon the movement of the operating-liandle in order to prevent the total-key from being operated whenever the handle 5 is in other than home position. The error-key also locks the totalkey against operation, but necessarily does it before the handle is operated.

ZocZ'z /M/ t/Iu wrror-lw .*lteferring to Fig. (5, it will be seen that a spring is connected to the downward extension 56 of lever 31, which downward extension is provided with a shoulder forming a hook. With this hooked lower end cooperates a lever pivoted at 57, said lever being substantially in the form of a bell-crank lever, having a hooked end 58 and a curved striking end 59. A spring 60 connects the parts 56 and 58 and holds them in such position that when the error-key is depressed the hooked end of the bell-crank lever will engage the shouldered extension of the error-key and hold said error-key down in a locked position until the hooked end of the bell-crank lever is forced out of engagement therewith. This latter is accomplished by the crank-arm 61 on the shaft 24-, which crank-arm, as shown in Fig. 2, is connected to and operates the ribbon-spool. hen the error-key is depressed the curved extension 59 falls down in the path of the c1anl arm 8. The lower end of lever e9 cooperates with l 6l,whose normal position isindicated in dotted lines in Fig. 6, and when the handle is operated said crank-arm engages the curved extension 59 and lifts it to its normal position, which when established releases the errorkey and permits the spring 55 to restore said error-key. In its restored position the errorkey holds the bell-crank lever and its curved extension 59 out of the path of the crank-arm 61, so that at each operation of the machine the crank-arm 61 will only slightly engage and hold the extension 59.

Retaining the total in the mac/tiae.1n the ordinary operation of the machine, as above described, in the absence of our improved error-key the operation of the total-key will result in the printing of the items on a strip of paper, after which the machine will automatically clear itself, there being no means of retaining the total in the machine. By the presence of our improved error-key and its connections if it is desired to obtain a total and retain said total in the machine after a series of items are set up on the keyboard and entered in the totalizer the total-key is operated as usual, after which and before the handle 5 is manipulated the error-key is operated, so that when the handle is pulled forward the total will be impressed on the strip of paper, and instead of the machine clearing itself the total will be retained in the totalizer and carried forward. This operation will be understood from what has been said before concerning the error-key holding the totalizertrains in mesh with the item-trains. However, to describe this operation more specifically it is only necessary to state that the operation of obtaining a total is to reversely rotateall of the totaliZer-trains by the movement of the handle 27, so as to set the itemtrains a proportionate distance,and the meshed type-wheels with their double set of type will present in the printing-line'the total as it appears in the totalizer. In the ordinary operation of the machine when the handle is pulled forward the type-hammers make a printing impression of the total on the strip of paper, and then raising the totalizer-trains, which have been restored to Zero to move the itemtrains to indicate the total, said totalizer-trains will be at a Zero position, and the handle after the printing impression will restore the itemtrains also to zero position, which will result in clearing the machine. If the totaliZer-lever is operated when the totalizer-trains are in mesh with the item-trains, it will be seen from the above that the totalizer-trains are moved to a zero position and the item-trains are moved to a position corresponding to the former position of the totalizer-trains Should the error-key be now operated, (before the handle is pulled,) so as to prevent the totaliZer-trains from being thrown out of mesh with the item-trains, it will be obvious that the total will be printed by the type-hammers, and when the item-trains are restored to Zero position, as they will be by the continued movement of the handle 5, the meshed totalizer-trains will be moved back to exactly the position they occupied before the total-key was operated, and consequently the total will be retained in the machine.

In the above description of the operation of the error-key we referred to the fact that the yoke 47 would prevent the type-hammers from printing whenever the error-key was operated, and with respect to retaining the total in the machine we have just stated that if the error-key was operated after the totalkey was depressed the total would be printed on the strip of paper and retained in the totalizer. It is obvious that if this is done some means must be provided for permitting the type hammers to deliver their impacting blows after and during the time that the totalkey is depressed. in the construction of the patented machine there is a cam-arm 62, which is employed in connection with the typewheels in printing zero characters to the right of any figure to be printed. This arm when the total-key is depressed swings on a pivot at its lower end, so that its upper end comes in contact with a stud 63 on the lower end of a lever 64. This lever is mounted in suitable brackets secured to the framing of the machine and carries at its upper end a stud 65, which normally rests in a notch in the end of a rock-arm 66, secured to the rock-shaft 46.. Thus when the total-key is depressed the stud 65 is moved out of the notch in the end of rock-arm 66 and elevates the yoke 47 above the shoulders 48, so that irrespective of the fact that the error-key may be subsequently operated before the handle is pulled the typehammers will make their printing impression in the ordinary way. This rocking of shaft 46, which results in enabling a printing impression to be made of the total when the error-key is operated to retain the total in the machine, also throws the paper-feeding mechanism in commission. It was stated before that whenever the error-key was operated the paper-feeding mechanism was rendered inoperative; but it is obvious that when a total is printed and retained in the machine the paper should be fed. Otherwise the next item would be printed over the total which was taken and retained in the machine. To permit the paper-feeding mechanism to operate when the total is retained in the machine, the rock-shaft 46, which is operated by the depression of the total-key, will through the connected members 45 and 48 raise the link 42, the elongated slotin link 42, which receives the end of the shaft 16, permitting this without disturbing said shaft and its carried totaliZer-wheels. The elevation of link 42 will cause the stud 51 to rock the lever 49 and move the stud 50 from engagement with the paper feeding pawl 8, as in the ordinary operation of the machine, so that said paperfeeding pawl 8 will when the handle is pulled advance the strip of paper the proper distance.

- We are aware that in adapting our invention to the particular machine shown and described in the Hopkins Patent No. 683,939 we have been obliged to meet conditions as they exist in said patented machine, and in illustrating one form of mechanism for accomplishing the results above described we do not wish to be limited to the exact form of that mechanism, except as such limitations are expressed in the claims, as there are various modifications of our improvement which could be made and used without in the least departing from the nature and principle of our in vention. Furthermore, while we have described our improvements as being applicable to one particular type of machine the said improvements may be applicable to other types of machines, and therefore we do not wish to be limited in the application of our improvements to the particular type of machine herein referred to.

In the above we have referred to an operating-handle as a medium through which power is transmitted to drive the machine. It is obvious that instead of a handle, which enters into the construction of a manuallyoperable machine, amotor could be employed, and therefore in the following claims we will refer to the shaft upon which the handle 5 is mounted as a power-driven shaft, and such expression will be understood as including within its meaning a manually or machine driven shaft.

We are aware that many minor changes in the construction, arrangement, and combination of the several parts of our device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of our invention.
